LAS VEGAS (AP) Consider them the concept cars of casinos.

Whether shooting down enemy planes, strumming a guitar-shaped controller to hit the right notes or swiping a table-top screen to grab the best set of cards first, the new wave of slot machines are looking a lot like an arcade game.

Until they made their debut at the annual Global Gaming Expo in late September in Las Vegas it wasn't entirely clear what "skill-based slots" might look like when Nevada lawmakers and gambling regulators opened the door to slot machines requiring little or a lot of skill rather than simply random chance.

California-based Gamblit says it expects its games to be a reality next year. That's after final regulations are passed and games are tested.
